Some Background On Van der Sloot Family Situation Reliable, independent sources spoken with today point to what seemed like preferential treatment toward Joran v d Sloot early in the investigation which possibly contributed to difficulties now being encountered in the search and investigation as regards the disappearance of Natalee Holloway.
One point made was that a search of the vehicle showed no traces of hair bel;onging to the Alabama teenager in the car driven by the Kalpoes that night, even though all known accounts place her in the vehicle at one time or another. This suggests that the car was cleaned above and beyond what one might normally expect sometime after young Natalee was known to have been inside.
That possible preferential treatment is not lost on all of the the Aruban people, many are now blaming the Van der Sloots for bringing recent troubling developments to the tiny island.
Those sentiments are being acted out in acts of vandalism, including at least one incident wherein a rock was throw through a window of their home, as well as damage to the front gate seen recently on reports on Fox News, and possibly other minor acts of vandalism as well.
Additional reports strongly suggest that prior to this incident, Paul v d Sloot was seriously considering moving his family off the island and back to his town of origin, Boxtel, cited here. The move would likely have been the result of his declining prospects for employment. It's been reported that he was offered a teaching position at a local scool, but he did not find the terms of the position acceptable. Other alleged attempts at seeking suitable employment were also said to have been unproductive.
The timing of that move would have coincided with Joran's going off to college. Now it is believed that should Joran v d Sloot be released, or found innocent of any wrong doing, it is likely the Van der Sloot family will likely make a timely move.
